Question

Height of a gravity dam of elementary profile, whose base width is B and specific gravity of material is G will be (For no tension condition)

• A. $B\sqrt{G}$
• B. $\sqrt{BG}$
• C. $BG$
• D. $B/\sqrt{G}$

Answer 1

The correct option is A $B\sqrt{G}$

For no tension condition,

$\text{Base width}=\frac{H}{\sqrt{G-C}}$

Where C = uplift pressure.

If uplift is not considered,

$B=\frac{H}{\sqrt{G}}\text{then height, H =}B\sqrt{G}$
